HA-106 < REMOVAL AND INSTALLATION > [WITHOUT HEAT PUMP SYSTEM] COOLER PIPE AND HOSE 2. Remove bolt (A), and then disconnect low-pressure flexible hose (1) from low-pressure pipe (2). CAUTION: To prevent the inclusion of foreign matter, use a cap or vinyl tape to seal off the connection ports of the hose and pipe from the atmosphere. 3. Remove bolt (A) and then disconnect low-pressure pipe (1) from expansion valve. CAUTION: To prevent the inclusion of foreign matter, use a cap or vinyl tape to seal off the connection ports of the pipe and expan- sion valve from the atmosphere. 4. Remove cowl top extension. Refer to . 5. Move electric water pump 1 to secure work space. Refer to 6. Disconnect low-pressure pipe from the vehicle. INSTALLATION Note the following items, and then install in the reverse order of removal. CAUTION: • To prevent degradation in insulation performance, use special electric compressor oil as the com- pressor oil. • In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compres- sor oil and instead always use new oil. The use of oil including the conventional PAG oil may degrade the performance of insulation. • To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant leakage. Also be careful that a fluorescent agent never enter the oil. • To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil to the O-ring prior to installation. • Perform a check for refrigerant leakage when charging with refrigerant. Refer to . JMIIA2671ZZ JMIIA2673ZZ |
